An observational study in Transthorcic Echocardiography, Stable Angina Pectoris and Coronary Artery Disease, sponsored by Tianjin Chest Hospital. Recruiting at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-07-18.
Sponsored by Tianjin Chest Hospital · Observational
The investigator aims to prospectively enroll patients who were referred for transthorcic echocardiography (TTE) for the assessment of stable chest pain (SCP) suspected of obstructive coronary artery disease (CAD). All patients underwent TTE according to established guidelines and local institutional protocols. This study will determine if TTE-based imaging evaluation can provide more informaton to improve clinical management for SCP, including fewer MACE and better decision-making of downstream investigations and therapeutic interventions.
343 studies on the registry are indexed under Angina, Stable; 56 are open to participants now.
This study's planned enrollment of 50,000 is above the median of 508 across 103 observational studies indexed under Angina, Stable.

Diagnostic Test: TTE
All patients underwent TTE according to established guidelines and local institutional protocols. The imaging data were evaluated using different image post-processing software to comprehensively analyse anatomical, functional and histological information of coronary.
Major adverse cardiovascular events
Time frame: 10 years
Invasive coronary angiography
Invasive coronary angiography occurred at follow-up after TTE, attributed to TTE results or unplanned.
Time frame: 10 years
Medication prescription
Change for medication prescription of antiplatelet agents, anti-ischemic drugs, lipid-lowering agents, angiotensin-converting enzyme inhibition and so on, attributed to TTE results or unplanned,
Time frame: 10 years
Coronary revascularization
PTCA, PCI or CABG occurred at follow-up after TTE, attributed to TTE results or unplanned.
Time frame: 10 years
Started Jan 2025 (actual). Primary completion is estimated for Dec 2030, 71 months after the start.
Of 52 observational studies under Angina, Stable, half reached primary completion within 47 months of starting (the median), counting those still running; a quarter within 27 and three quarters within 79. This study's planned 71 months is above that.
